Q: Is Excalibur Prime ever coming back?

A: No, he’s not. Excalibur Prime was offered to Warframe’s founders who believed in Warframe early in its development. There would be no Warframe without their support, and Excalibur Prime is how we acknowledge their invaluable contribution. Excalibur Prime was offered once and represents that history, so he will not be released again.

We are delighted that Warframe has grown and that our community is so unique and amazing. Even as we remember that our founders are Warframe’s foundation, Warframe is defined by all Tenno. We will continue to make more great Warframes, Prime Warframes, and content for all of our players!
